Firstly congratulations. :D it's great news that you're having support. Cramping is normal, through pregnancy, things need to stretch and move, it can be uncomfortable. When you book in with your midwife/doctor you can then speak with them. X
Yup. Very normal. Sometimes feels like PMS day after day.... Good luck!
As long as it's not accompanied by bleeding it's very normal to have cramping. If it's lower stomach is probably round ligament stretching. You can take a couple Tylenol and it should help. Also sometimes a warm bath helps as well loosen everything up. The other very common thing that can cause quite severe cramping is constipation. Also very common in pregnancy and very uncomfortable. :-/ hope you feel better soon tho
